Close to 10% of the French population is Muslim (predominantly Arab, but also Sub-Saharan African), with much higher numbers than that in urban metropolitan areas. Moreover, because most Third World people breed at astronomical rates (prolifically and at a young age), that 10% will be more like 30-40% within a couple of generations. If that isn't a case of being "overrun," I don't know what is. Does the population need to be 100% non-European before you consider it "overrun"?
Secondly, the Algerian French are highly integrated and many are "Muslim" as much as much of France is "Christian" - like Rachida Dati
According to the French Government, which does not have the right to ask direct questions about religion and uses a criterion of people's geographic origin as a basis for calculation, there were between 5 and 6 million Muslims in metropolitan France in 2010. The government counted all those people in France who migrated from countries with a dominant Muslim population, or whose parents did. Only 33% of those 5 to 6 million people (2 million) said they were practicing believers
Still too much - I grant you -- in fact I would say any number > 0 is too many Mohammadens
There is a problem with the new migrants yes - uneducated and if coming from non-Syria then radicalized.
But you exaggerate by saying 1. EUROPE is overrun -- this is France we're talking about, not Poland, not Italy
and
2. Europe is OVERRUN - the numbers are bad, but less than the number of Latinos in the US.
